S =  pi * r * (given degrees/ 180)   .....where S is the arc length

So

r =   [ S * 180 ]  / [ pi * given degrees]

4x^2+20x+25=0

which would be 1 real rational?

I don't know what you mean by "equivalent".....but we can solve this

4(x-2)<7x+1      simplify

4x - 8 < 7x + 1       add 8 to both sides and subtract 7x from both sides

-3x < 9                  divide both sides by -3 and reverse the inequality sign

x  >  -3

Thanks so muchh! :D :D

By factoring

x^2 + 2x + 1   = 0     can be factored as

(x + 1) (x + 1)  = 0

And setting either factor to 0  and solving, we have that 

x + 1 = 0      subtract 1 from both sides

x = -1

I'm not sure as to what you're calculating, but,  if we're asking the probability of a 7  or the probability of a double, we have :

P ( 7 or a double)  =  P(7)  + P(double)  - P(7 and a double)

The last term is 0.......no doubles  equal 7

P(7)   .......there are 36 possibilities when we roll 2 dice........the probability of a 7  =  6/36    ....and the probabilty of a double =  6/36

So

P(7 or a double)  = 6/36   + 6/36  -  0      =   12/36  =  1/3

First.. Do 72 divided by 514.. Then Times it by 100. :)

Melody say that it would be wise to do that, so everyone does not get mixed up.

Thats getting old

LOL! why not math? ;)

30 * 10  = 300

And we dont need to know ur name..... Whatever........ -.-

I dont think thare is a possible answer for that?

1. The probability that she wins the first 3 games and loses the last 2 is:

.(.82)(.82)(.82)(.18)(.18)= about 1.786%

2. The probability that she will win at least 1 game  = 1 - probability that she doesn't win any games =

1 - (.18)^5  =  > 99%

i cant say hi atleast? i just got done with some mathhh

-Hayley

TBH this is for math....... -.-

I got it myself, it's 14 and 31.5. No need to answer.

Do you mean 10^30. That's a nonillion according to wikipedia.

      What is (x-7)(x+8) simplified=x (x+1) - 56

Simplify the following:
2 (x-4)-3 (4 x+5)

2 (x-4) = 2 x-8:
2 x-8-3 (4 x+5)

-3 (4 x+5) = -15-12 x:
2 x+-15-12 x-8

Grouping like terms, 2 x-12 x-15-8 = (2 x-12 x)+(-8-15):
(2 x-12 x)+(-8-15)

2 x-12 x = -10 x:
-10 x+(-8-15)

-8-15 = -23:
-23-10 x

Factor -1 out of -10 x-23:
Answer: |  -(10x+23)

hmm lets see...9+1=10 10+1=11 11+1=12 12+1=13 13+1=14 14+1=15 15+1=16 16+1=17 17+1=18 18+1= 21!!!!!!!!!!!!!!!!!!!!!!!!!!!! ITS JOHN CENA!!!!!!!!!!!!!!!!!!!!!!!!!!!DEEZ NUTS!!!!!!!!!!!!!!!!!!!!!!!!HAHAHAHAHAHA

Jk

19! Orrr... 21

9=3*3 10=5*2 so now 5*3=15 and 3*2 equals 6. add 15 and 6 which equals 21

-Hayley

21!!!!!!!!!!!!!!!!!!!!!(no i am not stupid)
